experiment was to determine the effect of temperature on the rate of movement of Porcellio scaber. Our prediction was that P. scaber would have faster rates of movement in hotter temperatures. We expected this response as P. scaber is an ectotherm. Hence‚ its body temperature is directly determined by the temperature of its environment (Mellanby 1939). Løkke and van Gestel (1998) stated that the rate of the metabolism is controlled by the environmental temperature for ectotherms. As seen by Wieser‚ cited

Optic nerve sheath diameter (ONSD) The anatomy of the optic nerve sheath : The intraorbital section of the optic nerve extends from the globe‚ where it inserts medially‚ to the optic canal located in the lesser wing of the sphenoid bone. It is encased by a meningeal sheath consisting of dura mater‚ arachnoid mater and pia mater. Cerebrospinal fluid is contained in the trabeculated subarachnoid space and is continuously and slowly filtered. As a result the optic nerve sheath is in direct

To begin the analysis‚ the properties of the air at the base of the tower were examined. The wet and dry bulb temperatures of the air at the inlet were used to find the humidity‚ humid volume‚ and enthalpy of dry air. For example‚ in the first trial the dry bulb temperature was 22.5⁰C and the wet bulb was 16.5⁰C‚ and the properties found from the psychrometric chart are listed below. H_bottom=0.0095 kg/(kg dry air) V_bottom=0.85 m^3/(kg dry air) h_bottom=47 kg/(kg dry air) Then‚ the cross-sectional

Introduction: The purpose of this experiment is to measure the effects of changes in temperatures and pH on enzyme activity in skeletal muscle‚ particularly the activity of lactate dehydrogenase (LDH). LDH is a glycolytic enzyme which converts pyruvate to lactate in the following equation: LDH Pyruvate+ NADH ------------ Lactate + NAD The reaction above can move in both directions‚

JUICES WHAT IS THE EFFECT OF TEMPERATURE ON VITAMIN C IN FRUIT JUICES? The purpose of this experiment is to determine if the difference in temperature will damage vitamin C in any type of fruit juices. Five different temperatures of fruit juices will be used(5‚ 22‚ 50‚ 70‚ 90) degree Celsius to see how temperature affects the loss of vitamin C in fruit juices. The amount of vitamin C in the fruit juices will then be recorded to see if an increase in temperature will affect the amount of concentration

A2 Practical Investigations Title: The effect of Temperature on the growth of Aspergillus oryzae Develop a Hypothesis This particular investigation is to discover how a range of temperatures effects the growth rate of the fungi Aspergillus oryzae. Most fungi’s tend to survive within the temperature range of 5-35oC‚ with the optimum depending on their normal environmental temperature. The fungi Aspergillus oryzae is heterotrophic which means they taken in their food from dead organic matter and cannot

biochemical reactions in which one glucose molecule is oxidized into two pyruvic acid molecules and a small amount of adenosine triphosphate (ATP). Generation of high energy molecules are used as cellular energy sources in aerobic and anaerobic respiration. The products formed through glycolysis usually enter into the citric acid cycle and the electron transport chain to produce more energy. Fructose enters the glycolytic pathway through the liver or skeletal muscle. For example‚ in the liver‚ fructose
